Vulnerability from github – Published: 2026-03-31 23:57 – Updated: 2026-04-20 23:45

Summary

OpenClaw: Gateway chat.send ACP-only provenance guard could be bypassed by client identity spoofing

Details

Summary

ACP-only provenance fields in chat.send were gated by self-declared client metadata from the WebSocket handshake rather than verified authorization state.

Impact

A normal authenticated operator client could spoof ACP identity labels and inject reserved provenance fields intended only for the ACP bridge.

Affected Component

src/gateway/server-methods/chat.ts, src/gateway/server/ws-connection/message-handler.ts

Fixed Versions

Affected: <= 2026.3.24
Patched: >= 2026.3.28
Latest stable 2026.3.28 contains the fix.

Fix

Fixed by commit 4b9542716c (Gateway: require verified scope for chat provenance).

Title

OpenClaw < 2026.3.28 - Client Identity Spoofing in chat.send Gateway Provenance Guard

Summary

OpenClaw before 2026.3.28 contains an authorization bypass vulnerability in the chat.send gateway method where ACP-only provenance fields are gated by self-declared client metadata from WebSocket handshake rather than verified authorization state. Authenticated operator clients can spoof ACP identity labels and inject reserved provenance fields intended only for the ACP bridge by manipulating client metadata during connection.
